Light dependent reactions are carried out both on and in between photosystems. This process is like the last stage of aerobic respiration in that both:. a. reaction sequences carry out electron transfer phosphorylations.
b. processes generate ATP.
c. processes involve electron flow.
d. systems are lodged along and within a membrane surface.
e. all of the above.

e. all of the above

Explanation:

Photosynthesis and respiration are two complementary processes.

Photosynthesis occurs in chloroplasts. The electron transport chain is placed in the thylakoid membrane, where it occurs light-dependent reactions.Respiration occurs in mitochondria, in the internal membrane, where is the electron transport chain.Photosynthesis needs solar radiation to produce organic compounds.The respiration process needs organic compounds to obtain chemical energy.Photosynthesis transforms CO₂ into organic compoundsRespiration transforms organic compounds into CO₂.In the photosynthesis process occurs a release of oxygen, which is used during the respiration process.  Both processes are part of the carbon biological cycle.Both processes use electron transport chains to capture energy, which will be used in other cellular reactions.Respiration´s final products are CO₂, ATP, and waterPhotosynthesis´s final products of light-dependent reactions are oxygen, ATP, and NADPH.  

The answer is c) tons

Then it is june the conclusion to the second sentence is just restating "if it is june then it is summer"
